Most of our clients today have been looking for the GDPR compliancy feature by using SyncApps. This is one of the most important things to do before sending campaigns to your clients. Here's how you do it:
First, you will need to go to your MailChimp Master List and set the GDPR sign-up consent forms. See the guide here.
To make Groups visible or other data fields these can be one on a per List basis in MailChimp.
Groups if visible on Form and using our Checkbox Field Add-On would enable them to sync back to your CRM. Unfortunately, the Groups are visible on the form yet in Step 4 are not available but mappable using our Checkbox Field feature only.
Add-Ons are available on every Trial and in paid plans.

These fields for GDPR are not mappable in Step 4 unfortunately, after checking with MailChimp, yet they might be in future API releases they stated as these are only for the List permissions in MailChimp.
